One candidate that Dr. Cummings described as the “darling” of obesity researchers would be a drug that could stimulate a brain structure called the melanocortin-4 receptor, to decrease appetite and cause weight loss. But side effects always loom, and one drug tested in animals made them lose weight but also caused erections.
“That may sound great, but when the erections are unsolicited and prolonged, that’s a bad side effect,” Dr. Cummings said.

If this isn’t fodder for Jay Leno, I don’t know what is. Newly-thin people getting “unsolicited and prolonged” erections, as described by a Dr. Cummings. 😀
